A 3D pie plot is much like a normal pie plot but in a 3D setting. You can control the apperance by specifying the angle of attack for the pie. A small angle show a very "flat" pie while a large angle shows almost a 2D pie.
Please note that a 3D pie is much more CPU intensive to draw then the normal pie. To reduce the time you might want to keep the height of the pie as small as you think looks good. The height has a direct linear impact on how long it takes to draw a 3D pie. (See SetHeight()).
To view a 3D pieplot you start by constructing a PieGraph() and then adding a numerb of constructed PiePlot3D to this graph.

Specify slice labels for 3D pies. Positoin specify the fraction of the radius wher the labels should be positoined. A values of 1 will position the labels outside the pie.

The labels may include an optional sprintf() formatting string. Before stroking the label to the graph it will be formatted with the actual value (absolute or percentage) depending on what has been specified with the SetLabelType() method.
